After the two were separated, the 14-year-old girl stepped into the altercation and tried to pull the other girl away from the officer. When the officer would not release the girl who was in the fight, the 14-year-old struck him in the face, Kennedy said.

The 14-year-old was charged with assault on an officer, interfering with an officer and breach of peace.

Kennedy said the bureau will determine whether she will be released to the custody of her parents or sent to the Juvenile Detention Center at Bridgeport.

The officer was uninjured in the assault.

Correction: An earlier version of this story misstated which school the 14-year-old arrested for striking a police officer attended. The student attends the Academy of Information Technology & Engineering.
